Silver Member Username: The_image_dynamicSan Diego Post Number: 301 Registered: Dec-06 | Sounds like wiring issues maybe? You shouldn't need a HO alt with those two amps unless that stock Chevy one is really weak. But it wouldn't hurt, except your wallet. |

For 500wrms, I would go to 4 awg. Its a bit overkill but if you upgrade later... Also, power wire and ground should be the same size. |

Silver Member Username: The_image_dynamicSan Diego Post Number: 302 Registered: Dec-06 | Exactly right David, I was just looking that up when you posted. Something is wrong in your wiring like I said..... do everything Marc just posted and also check for shorts, sketchy crimps etc. Here is a step-by-step for the Big 3 if you don't know about that: http://www.the12volt.com/installbay/forum_posts.asp?TID=73496&PN=1 |
Bronze Member Username: StevefrenchPost Number: 80 Registered: Jan-07 | so my ground might not be good enough, its got like 1/2 the wires on the bolt....could the ground be the problem even though the amps are both on??? and why would my deck shut off.... |
Silver Member Username: Solobaric4lifeSeminole, Al United states Post Number: 247 Registered: Jan-07 | all u gotta do it look on it and see for example it will say, 105A thats a 105amp alt on stock alt's ^^^^, but i would get higher amp |
Silver Member Username: Solobaric4lifeSeminole, Al United states Post Number: 248 Registered: Jan-07 | i didnt notice that amp, u wont need high alt unless u upgrade |
Bronze Member Username: StevefrenchPost Number: 82 Registered: Jan-07 | so then why does it cut out when i bump too loud?? system= breakin my balls lately |
Bronze Member Username: DchrsfPost Number: 14 Registered: Feb-07 | which headunit do you have? If pioneer (OEL display) you can check the voltage on it. See if its below 11v at any time. You can use a Digital Multi meter also to check voltage coming your the bat or alt. |
